Precious Metal Refining is an art form that dates back to Ancient Rome.
The classic fire assay process that is used for refining precious metals is the gold standard (no pun intended) method in the industry.
With a fire assay, precious metals such as gold and silver are separated from non-precious metals by fusion. When performed properly it has an accuracy of 1 part in 10,000.
Core Scientific goes a step further than the classic fire assay with their multi-step process:
- Initial screening of your material
- Primary melt
- Inductively Coupled Plasma (ICP) – Mass Spectrometry.
Other materials like platinum, palladium, and low-grade materials need to go through a separate process ICP (inductively coupled plasma). In a nutshell, ICP ionizes the sample to isolate certain ions and identify them.
The benefit of working with a refinery that uses these cutting-edge, proven methods is they extract the most precious metals from your material. When you start to work with a refinery it is important that you find out if the refinery has an on-site laboratory. This is crucial as many “refineries” outsource the refining of the material. This equates to less money for you in the end.
